Abstract: A pump-less buoyancy engine for an autonomous underwater vehicle (AUV) includes a buoyancy reduction structure (302) without a hydraulic pump for reducing the buoyancy of the AUV to cause the AUV to descend in the water; and a weight dropping structure for dropping prepackaged weights out of the AUV to cause the AUV to ascend in the water, where the AUV moves forward when descending and ascending.
